Sign Language Interpreter Services Code Conversion Policy Overview

November 29, 2018

Effective for dates of service on or after January 1, 2019, sign language interpreter services currently billed using HCPCS Level III local codes will be converted to a specified HCPCS Level II national code.

Providers submitting claims with dates of service on or after January 1, 2019, must include the appropriate HIPAA-compliant HCPCS Level II national code described in the Sign Language Interpreter Services Crosswalk published October 2018.

For dates of service on or after January 1, 2019, HCPCS Level III local codes Z0324, Z0326, Z0328 and Z0329 will be discontinued, and any claims submitted with these codes will be denied. HCPCS Level III local codes Z0324 and Z0326 will be replaced by HCPCS Level II national code T1013 (sign language or oral interpretive services, per 15 minutes) and revenue code 0969 (other professional fees) for UB-04 claim forms or ANSI 837I transactions.

Modifier code HM (less than bachelor degree level) will be applicable when billing for sign language interpreter services for dates of service on or after January 1, 2019. Modifier code HM is used to denote that the rendering provider is a certified sign language interpreter.
